February 18Feb 18 Hello all,My Unraid server is slowly running out of space and I need to add a new disk to it. Today I have 1 x 6 TB WD red plus for parity, another 6 TB red plus and 1 x 4 TB Seagate for data. All my disks are CMR.Now, given the current market prices I am considering adding a cheap 6 TB WD blue (WD60EZAZ) which is an SMR drive. That drive would be formatted as a single drive ZFS pool because I like snapshots.My data is fairly static, the NAS is mostly used for archive (family pictures, ISOs, software installers, and movies). I have a few shares that are mounted on a PC and for which the content is a bit more dynamic but I can exclude that disk for these shares and that should not be a major problem.Is this a bad idea?I read that SMR drive can cause rebuild to fail because of timeout, is this true? Would this be a problem in my setup?Thank you for your help.
